SCREEN BRIGHTNESS ADJUSTMENT METHOD AND HELMET

WIPO Patent Application WO/2021/120564

A1

A screen brightness adjustment method and a helmet. The method comprises: a baseband chip acquires original image information collected by a camera, and obtains image target brightness information; the baseband chip sends an instruction to an optical waveguide control chip, the instruction carrying image target brightness data; and the optical waveguide control chip receives the instruction, and adjusts an optical waveguide display screen according to the image target brightness data. By extracting a brightness signal of an image photographed by a camera so as to adjust the brightness of an optical waveguide screen, the environmental brightness of a photographing scenario of the camera can be realistically reflected, instantaneity is high, and reliability is good, thus it is more comfortable for the human eye to view an optical waveguide screen.
